Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic malignancy with a female predilection, typically presenting as swelling in anterior region of mandible. CCOC was classified as a malignant neoplasm of odontogenic origin by the WHO in 2005 as it exhibits an aggressive growth pattern, local recurrence, and tendency of distant metastasis. Histologically, CCOC is characterized by sheets and islands of vacuolated/clear cells. Since clear cells are present in few odontogenic tumors, salivary gland neoplasms, and metastatic tumors to the jaws; presence of clear cells in a lesion of head and neck area poses a diagnostic challenge. Knowledge about the clinical course, histopathologic pattern, and immunoprofile of CCOC aids in differentiating it from other clear cell tumors. Herein, we present a case of CCOC in anterior mandibular region of 60-year-old female patient with an emphasis on its differential diagnosis from other clear cell lesions of the jaws.
